摘要
W波段（75~110GHz）作为一个新的RF（射频）波段,相比于其他波段有着更宽的带宽和更高的频率,在这个波段能够为移动数据通信提供千兆的无线链路,这已经成为下一代无线通信系统的一个热点话题。实现W波段大容量通信系统有多种方法,如高阶调制、天线复用和多频带调制等,目前这些技术从调制效率、频带利用率和带宽宽度等多方面已实现了系统的优化。文章深入介绍了W波段大容量光纤无线融合系统的背景、研究成果及技术支持,以期为未来的研究提供参考。
As a new Radio-Frequency（RF）band,W-band（75~110GHz）has wider bandwidth and higher frequency in comparison with other bands,enabling itself to provide mobile data communications with gigabit wireless links,which has become a hot topic about the next generation wireless communication systems.There are a variety of W-band technologies for realizing large-capacity W-band communication systems,e.g.high-order modulation,antenna multiplexing and multi-band modulation.These technologies optimize the system in terms of modulation efficiency,band utilization and bandwidth.This paper introduces in depth the system background,research results and technical support,so as to offer a reference for future researches.
